2026-04-12

Need to sign a PDF but don't have a printer? You're not alone. Millions of people still print, sign, and scan documents every day — a process that wastes time, paper, and ink. The good news is that you can sign any PDF digitally in just a few seconds, completely free, without leaving your browser.

Three Ways to Sign a PDF Online

Most online PDF signing tools offer three methods. Draw your signature using a mouse, trackpad, or touchscreen — this gives the most natural look. Type your name and choose from script-style fonts that mimic handwriting. Or upload a photo of your handwritten signature and place it on the document.

Is a Digital Signature Legally Valid?

In most countries, yes. The US ESIGN Act, the EU eIDAS regulation, and similar laws in Japan, Australia, and many other jurisdictions recognize electronic signatures as legally binding for most document types. Exceptions include certain government forms, wills, and documents requiring notarization.

Tips for a Professional-Looking Signature
